Description:Something changed in libpri after 04/21/05 which causes our
asterisk to be unable to send calls via PRI.

I just upgraded our primary asterisk server to most recent everything last night.

I did the following steps to find where the breakage was (I actually started
with 4/18 and progressed up daily until I got breakage):

cvs co -D "April 21, 2005" libpri
cd libpri/
make; make install
cd ../asterisk/
make bininstall
Start up asterisk
load chan_zap.so
All 96 channels started, B and D
Able to recieve calls via PRI. Able to send calls via PRI

stop asterisk.
rm -f libpri/

cvs co -D "April 22, 2005" libpri
cd libpri/
make; make install
cd ../asterisk/
make bininstall
Start up asterisk
load chan_zap.so
All 96 channels started, B and D
Able to recieve calls via PRI
** NOT able to send calls via PRI **

I've attached 2 intense pri debugs. The date in the debug file corresponds
to which cvs version I checked out.

Each debug has the info for 1 call: 7134687866

Let me know if you need debug traces from the CO side. I can get them.

Here is the CLI output:

   -- Executing Dial("SIP/3013-c75c", "ZAP/R1d/7134687866|60|WT") in new stack

Oh, read the bug posting guidelines before putting a severity of type BLOCK.

you are the king! works again! what happened?

(sry..should have been major..but i felt that the changes "blocked" outgoing calls.)

It was sending the caller name information out over a facility IE and your telco was rejecting it for some reason.  I made it default to not send facility IEs and you have to explicitly enable this feature in zapata.conf.

Fixed in CVS
